Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen and bathroom accessories and relates to a pull-type water divider. Background Art

[0002] Existing pull-type water diverters generally include a water diverter body, a water diverter core, and a water diverter joint. The water diverter state is switched by the sliding of the water diverter core in the inner cavity of the water diverter body. Existing water diverter bodies and water diverter joints are mostly one-piece structures. For ease of installation, some technicians have designed the water diverter body and water diverter joint into separate structures. When the separate structure is designed, the water diverter body and the water diverter joint are connected by threads: an external thread is set at the lower end of the water diverter body, and an internal thread is set at the upper end of the water diverter joint. The water diverter body and the water diverter structure are fixed by the screw connection structure of the internal and external threads. This structure is prone to water leakage due to thread wear after long-term use, and it also makes installation difficult. Utility Model Content
